The main idea of this scheme includes adaptive speed transition and freeze-acknowledgement （freeze-ACK）. Adaptive speed transition can improve throughput and reduce delay in high bit error rate （BER） environment. Simultaneously, freeze-ACK is adopted to conquer frequent usage of feedback channel. Simulation shows that the scheme of combining adaptive speed transition with freeze-ACK offers great performance improvement in SRIO network.展开更多
